Can someone tell me why I have four separate drane plugs on my 1994 Harley Davidson Dyna custom lowrider?? I know about the transmission drain plug and one oil plug and also the chain case plug but I have one more plug it seems like it has oil in it all so... If necessary I can post a picture. Thanks
That one is not supposed to be removed if your referring to the one with tapered threads. Use a tapered pipe sealer on it and use care to not over tighten it.
You have a transmission drain, the actual oil sump for engine in the pan under the transmission and the primary chain and wet clutch oil drain.
And yes....

1. If you are going to work on your bike, get a HD Service Manual for your bike.
2. Read it.
3. Report back on your findings once read and comprehended.
NOTE:
The above information, while credible, is worth what you paid for it and should not be considered gospel.
Do due diligence, research and have a H-D Field Service Manual before working on your bike.
You will probably have many opinions and suggestions presented; make sure you research the person providing the helpful information as there are some who provide good information that is useful and some who speak out of other orifices with gibberish. You will figure out this quickly.
